DmWhat (xx0231@1)is this, numbers in your pocket

            AmI (x02210@1)remember when you

Used to throw those things away

DmWhy (xx0231@1)do you wanna keep in touch now

               AmWho (x02210@1)gave you a reason

To act so shady

DmBaby (xx0231@1)you know, you can call me anytime

                                      AmAnything (x02210@1)you needed I would give it to you

That's how much I care for you

DmYou (xx0231@1)wanna act now, never call me back now

Turning off your cell phone

                          AmGirl (x02210@1)you know that ain't cool

I don't understand baby

DmBaby (xx0231@1)it's a shame we gotta go through this

                 AmWe (x02210@1)can't even talk

Girl we don't even kiss

                         DmI (xx0231@1)never would've thought

We'd be breaking up like this

           AmBut (x02210@1)it's over now

It's over now

you get the point, jam on
